1 Claim.

The principal object of the present invention,

is to provide a convenient removable receptacle for blackboard eraserledges, ,to the end that from time to time chalk dust and other smallparticles of matter can be deposited in the receptacle and at some afterclass time the receptacle can be displaced and its contents dumped insome large trash depository.

In the drawings:

Figure 1 represents a fragmentary top plan view showing the receptaclemounted on a blackboard eraser ledge. I

Figure 2 is a vertical sectional view on the line 2--2 of Figure 1.

Figure 3 is a vertical sectional view on the line 33 of Figure 1.

Figure 4 is a sectional view on the line 3-4 of I Figure 1.

Figure 5 is a side elevational view of the insert frame.

Figure 6 is a fragmentary side elevational view of the cage.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 denotes an elongated eraser ledge such as isfound under most school blackboards.

This ledge is formed with a substantially square opening 6 into which isplaced a substantially rectangular-shaped frame 1 having side flanges 8,8 apertured to receive securing members such as screws 9, which aredriven into the ledge 5.

Certain lower edges of the frame I are flanged inwardly as at In andupon these flanges l0 rest the horizontal flanges of angle members I l.The upper end'portions of the legs of U-shaped straps l2, l2 are securedas by welding to the angle members H and these straps [2 taken with theangle members II define a cage for supporting a receptacle I3, which isopen at its top and preferably has a rounded bottom portion resting onthe bight portions of the straps l2 and a connecting member M whichbridges the bight portions of the U-shaped strap members l2, I2.

It can be seen that from time to time chalk can be discharged into thereceptacle I3 and as well other foreign matter. When it is desired todump the receptacle, the receptacle l3 can be pushed upwardly throughthe frame I and entirely removed. After its contents has been v dumpedin some large waste depository, it can be readily slipped back into thecage to repose as shown clearly in the drawings.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, claimed as new is:

A receptacle structure comprising a supporting member having an openingtherein, a frame disposed in the opening and having inwardly disposedflanges at its lower portion, a cage, said cage consisting of a pair ofU-shaped members bridged together at their upper and lower portions,said U-shaped members being provided with angle strips to bridge theupper ends thereof, said angle members having outstanding portionsdisposed over the flanges whereby the cage is supported, and areceptacle for disposition through the frame and in the cage.
